Answer: (3p^2 + 1) . (p^3 +4)

Step-by-step explanation:

Area of a rectangle equals length multiplied by width. Given length as 3p^2 + 1 and width as p^3 + 4

Area = 3p^2 + 1) . (p^3 +4)

This is so as 4 is not a cube and cannot be factored.

I hope this helps.

What is the area of the figure:

Luba_88 [7]

For this case we have that the area of the triangle is given by:

$A = \frac {b * h} {2}$

Where:

b: It's the base

h: It's the height

We have to:

$cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}$

The atura will be given by:

$sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}$

So, the area is:

$A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144$

Answer:

144

The caloric density of foods is a useful tool when comparing calorie counts. The table shows typical serving sizes for several f

mezya [45]

Answer:

Medium apple < Large hard boiled egg < raisins < cheddar cheese

Step-by-step explanation:

1. Cubic inch cheddar cheese ;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 69 / 17 = 4.0588cal/g

approximately 4.1cal/g

2. Large hard boiled egg;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 78 / 50 = 1.56cal/g, approximately 1.6cal/g.

3. Medium apple;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 72 / 138 = 0.52cal/g

4. Raisins;

Cal per 100g = cal(c) / grams(g)

Cal per 100g = 129 / 43 = 3cal/g

The foods with the lowest density to the highest is,

Medium apple < Large hard boiled egg < raisins < cheddar cheese

Solve the equation below for x. 100 = 25e3 In4 O A. 4 B. 3 e O C. X=In4 - 3 c In100 3. In25 O D.

Ray Of Light [21]

Dividing the given equation by 25 we get:

$\begin{gathered} \frac{100}{25}=\frac{25e^{3x}}{25}, \\ 4=e^{3x}\text{.} \end{gathered}$

Applying the natural logarithm to the above equation we get:

$\ln (4)=\ln (e^{3x})=3x\ln (e)=3x\text{.}$

Finally, solving for x we get:

$x=\frac{\ln (4)}{3}\text{.}$

Answer: Option A.
